ZenSim's story? Just a couple of Aussie lads who thought, "This industry is a bit sh*t, and we could probably make it a lot easier and a lot more fun".
So, say goodbye to the lame corporate vibe, and welcome to ZenSim. We're friendlier, more approachable, yet still competitive with a focus on sustainability.
In a nutshell, we're not your typical telco. We want to create a company where every customer counts, not just the new ones - and we're always open to your feedback so we can keep doing better.

What is a Travel eSIM?
Travel eSIMs explained
A travel eSIM is like a magic ticket to instant connectivity—no plastic, no swapping, no stress. Instead of fumbling with tiny SIM cards at the airport or getting ripped off by roaming charges, an eSIM (embedded SIM) lets you download a mobile plan straight to your phone. Just scan, activate, and boom—you’re online.
With a ZenSim Travel eSIM, you can stay connected in over 200+ countries without ever stepping into a store. Whether you’re chasing sunsets in Santorini, working remotely in Tokyo, or just need Google Maps to find the best tacos in Mexico City, our Travel eSIMs keep you connected without the hassle.
How does a Travel eSIM work?
It’s all digital, baby. Instead of physically inserting a SIM card, your phone downloads an eSIM profile that tells it which network to connect to. It’s like adding a new mobile plan—except it happens in seconds, and you don’t need a paperclip to open your SIM tray.
Here’s how easy it is:
- 🤜 Buy a ZenSim Travel eSIM before or during your trip.
- 🤜 Either scan the QR code or install the eSIM via our ZenSim app.
- 🤜 The eSIM will be activated once you arrive and you can browse like a local.
Why should you use a Travel eSIM?
Still using your home provider’s global roaming? Oof. You might be paying way more than you should. Travel eSIMs give you:
- ✅ Instant activation – No waiting, no delivery, no hassle.
- ✅ Affordable data – Say goodbye to those ridiculous roaming fees.
- ✅ Multiple plans, one phone – Keep your regular SIM active for calls while using your eSIM for data.
- ✅ Global coverage – Find Travel eSIMs for over 200+ countries with ZenSim.
Basically, a travel eSIM is the smarter, cheaper, and faster way to stay connected wherever you roam. So ditch the overpriced roaming plans, forget about airport SIMs, and travel like a pro with a ZenSim Travel eSIM.
